PMax campaign structure
PMax campaign strucutre is defined within the campaign on two types of “Groups”. Both types of groups are software objects or containers that aggregate other objects, to form a PMax campaign.
PMax Listing Groups: Provide a mechanism to group together similar products within the feed. You can create product groups using various attributes present in the feed. Typically this is used to bid similar products and product variants at the Product Group level.
PMax Asset Groups: Listing Groups are subgroups of similar product SKU’s within the product feed. In small campaigns, a listing group could contain all SKUs in the campaign, but usually, it is a subset, and multiple Asset Groups are present.
Listing Groups are each targeted with multiple targeting methods, allowing a split-test of targeting after the campaign is launched.
